CopilotKit Intelligence ADK

SkillRegistry and SkillToolset deliver one Learning container's published skills to standard ADK LlmAgent instances. The adapter supports google-adk>=1.17,<2. It does not patch arbitrary custom BaseAgent implementations.

from copilotkit_intelligence import Intelligence
from copilotkit_intelligence_adk import SkillRegistry, SkillToolset
from google.adk.agents import LlmAgent

async with Intelligence(api_key="your-project-key") as intelligence:
    registry = SkillRegistry(
        client=intelligence,
        container_id="your-learning-container",
    )
    await registry.initialize()
    agent = LlmAgent(
        name="assistant",
        model="your-model",
        instruction="Your application instructions.",
        tools=[SkillToolset(registry)],
    )
    # Use the agent with the application's normal async ADK Runner.
    # After all runners finish, release the registry's owned resources.
    await registry.aclose()

A registry can serve several explicitly selected agents. SkillToolset.close() does not close that shared application-owned registry. registry.aclose() closes a helper-created canonical client but leaves an injected client and HTTP pool application-owned. Startup errors are catchable and initialization can retry. status exposes immutable initialized, revision, mode, last_checked_at, stale, and last_error values.

SkillRegistry accepts client, api_key, api_url, container_id, revision, freshness_window, request_timeout, and debug. Durations use seconds and default to five. Debug defaults to false. Explicit values override CPK_INTELLIGENCE_API_KEY, INTELLIGENCE_API_URL, CPK_INTELLIGENCE_LEARNING_CONTAINER_ID, and CPK_INTELLIGENCE_SKILLS_REVISION. An injected canonical client supplies all connection configuration.

The toolset always exposes copilotkit_load_skill and copilotkit_read_skill_file, including for an empty container. Its native process_llm_request hook waits for an authorized snapshot before the model runs, then appends an alphabetical catalog. Developer-authored instructions outrank learned skills. The model chooses which skills to use. Tool discovery does not perform authorization, because ADK can suppress discovery failures.

Each pin belongs to the actual native session object and invocation ID. Parallel hooks and tools share that pin. A new run or resumed invocation receives a fresh native context and rechecks the registry according to its freshness window. The adapter stores no UUID, snapshot, or lock in session state or event deltas. Copied state cannot select another invocation's pin. Weak session ownership releases private pins when the invocation session is collected, including after cancellation or denial.

Tool results support manifest-listed UTF-8 text only. Unknown skills, unlisted paths, and binary files produce ADK function responses with an error field. The adapter never executes scripts or writes skill files. Completed tool output is ordinary model history and can be persisted by the host framework. Subagents follow native ADK behavior; attach the toolset explicitly to each LLM agent that needs skills.

Warm transient failures retain the previous snapshot indefinitely and mark status stale. Confirmed denial blocks new invocations. An explicit revision pins the complete skill set and never falls back to latest. Existing invocation pins stay unchanged while later registry refreshes complete.

Builds vendor shared private source into copilotkit_intelligence_adk._delivery. There is no dependency on another public adapter or a separate public core distribution. The canonical runtime dependency must be published with learned-snapshot and per-request deadline support before release. Its existing Runtime dependencies remain part of the installation.

Repository checks use Nx targets intelligence-adk-python:test, :test-minimum, :test-latest, :typecheck, :lint, :build, and :verify-distribution. The distribution check rebuilds the sdist outside the checkout and imports the resulting wheel without editable adapter source. Resumability tests use ADK's native experimental ResumabilityConfig; applications retain control over enabling that framework feature.
